vCenter Server Appliance Component Manager fails with an error when you first deploy it after an upgrade.

Problem

You deploy a vCenter Server Appliance instance and receive an error such as the following text:

"Firstboot script execution Error."

"The SSL certificate does not match when connecting to the vCenter Single Sign-On: hostname in certificate didn't match: <vcenter-b.domain.com> != <localhost.localdom> OR <localhost.localdom> OR <localhost>"

Cause

The vCenter Server Appliance instance names do not match the names in the SSL certificates. You must regenerate the certificates to get the correct Fully Qualified Domain Names.

Solution

Power on the vCenter Server Appliance 5.5 instance.

Log into the VAMI https://IP:5480.

Make sure that the correct IP address and Hostname are set in the Network Settings.
